i found these at a kmart or target or some such.
they seem kinda lightweight, but they do clamp on, and i like the stud connections.
blister pack- 1 black handle, 1 red + some wire terminals i didn't use.

quick-clamp terminals(for post terminal batteries)
east penn manufacturing co. inc. had them manufactured in china. east penn probably doesn't manufacture anything directly.
<$5 if memory isn't totally shot.
